Chrome: Finding that one annoying tab that’s playing audio in Chrome got a little easier back when the browser started showing which tab is playing audio. Now, in Chrome’s Dev channel, you can prevent multiple tabs from playing audio at the same time.
This feature works by only allowing one audio stream to play at a time. For example, if you’re watching a video on YouTube and an auto-playing add starts playing music, the YouTube video will be paused. This helps make sure that you don’t have several audio streams accidentally playing at once. To enable this feature, open up a new tab in the Chrome Dev browser and head here:
Here you can either set this feature to Enabled, or “Enabled (Flash lowers volume when interrupted by other sounds, experimental)”. This latter feature will lower the volume of the interrupted stream, instead of pausing it entirely.
